text: Keiko Hattori is a geochemist and mineralogist. She is Distinguished University Professor of Geochemistry and Mineral Deposits in the Department of Earth and Environmental Sciences at the University of Ottawa.
  Hattori is most known for her research on aspects of Earth's atmospheric and mantle evolution, as well as the formation of arc volcanoes and the generation of metal-fertile volcanic arcs. Her application of this knowledge has led to insights regarding the origins and locations of mineral deposits. Specifically, she has conducted research on the transfer of chalcophile elements (copper-like elements) from slabs to arc magmas through mantle wedges, as well as from arc magmas to mineral deposits. Additionally, her work has encompassed exploration geochemistry, where she has investigated the dispersion of metals from buried deposits including platinum and palladium in surface media. She was appointed as the 2022 International Exchange Lecturer of the Society of Economic Geologists (SEG), and has been the recipient of the Island Arc Award and the Takeo Kato Gold Medal.
  Hattori is an elected Fellow of the Royal Society of Canada and Mineralogical Society of America.
